SPECIFICATION forming part of Letters Patent No. 727,942, dated May 12, 1903.

Application filed August 14, 1902.

To (l/ZZ whom it may concern.-

Be it known that I, JOHN A. HEBB, a citizen of the United States, residing at Uniontown, in the county of Fayette and State of Pennsylvania, have invented certain'new and'usefulImprovementsin Coke-Drawing Machines, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of this specification, in which- Figure l is a plan view of my improved cokedrawing machine, showing it in position in front of an oven-door, portions of the conveying mechanism and the beam being broken out. Fig. 2 is a vertical longitudinal section on the line II II of Fig. 1 on an enlarged scale. Fig. 3 is a similar view at right angles to Fig'. 2, indicated by the line III III of Fig. 1.

Fig. 5 is a horizontal plan View of the under supportingframework and the mechanism thereon, partially shown in section and indicated by the lineVVof Fig. Fig. 6isaverticalsectional view of the machine on the line VI VI of Fig. 5, showing the traction-driving and clutchoperating mechanism. Figs. 7 and 8 are detail sectional views indicated by the lines VII VII and VIII VIII of Fig. 1, illustrating the means for rotating the turn-table. Fig." 9 is a vertical section on the line IX IX of Fig. 2.

My invention relates to ap 'aratus for drawing coke from the oven; and it consists of a traveling structure or framework provided with supporting-Wheels adapted to travel by traction upon supportingrails laid in front of a bank of ovens, such framework supporting conveying mechanism for carrying away the coke drawn from the oven, a rotatable table, a rake-beam mounted on the table, together with gearing for raising and lowering the beam and for giving it longitudinal movement in either direction, gearing for rotating the table, clutch mechanism and levers rotatably mounted on the framework, together with the various other operative elements and details of construction, as shall be more fully hereinafter set forth.

Related subject-matter is embodied in sepfieria] Nil-119,617. (No model.)

arate applications bearing the Serial Nos. 119,618, 119,619, and 119,620, filed August 14, 1902; No. 120.559, filed August 21,1902, and No. 125,644, filed October 2, 1902.

Referring now to the drawings, A represents the foundation-framework of a port able carriage upon which is supported for the purpose of providing lateral range a turntable B, upon which is carried the Various 6o operative and manipulative portions of the machine, with the exception of the convoyers, main shaft, traction driving-gear, and the prime mover. Theturn-tableB is supported upon casters or rollers 2, mounted in hearings in framework A, the turn-table being provided with a circular track 3 of any suitable design or construction, but preferably grooved, so as to assist in maintaining the turn-table in a central position.

1 is the main shaft, mounted in suitable bearings in the main framework and driven at its end by an engine or motor, which may also conveniently be a compressed-air or electric motor.

Extending at right angles to shaft t and on substantially the same level is a shaft 5, and centrally arranged at the middle of the turntable is a vertical shaft 6, the lower end of which rests in a step-box! in the main framework A and which is preferablyprovided with a row of ball-bearings 8 to reduce friction. V

Mounted on shaft 6 is a bevel-pinion 9 in driving engagement with a smaller bevelwheel 10 on shaft 4, while wheel 9 meshes into a similar wheel 11 on'shaft 5, and as thus connected when main shaftr' t isdriven the shafts 5 and 6 will be also continuously driven, shaft 6 operating at a somewhat slower rate of speed. From these main shafts all of the various operations of the machine aretra'nsmitted through the gearing, clutch, and lever mechanism, hereinafter described.

The turn-table B is rotated in either direction by a hand-wheel crank 12, connected to a shaft 13, mounted in support 14 andprovided with a bevel-pinion 15 in engagement with bevel 16 on the upper end of the shaft 17, which extends downwardly through the turntable. the upper face of framework A, into which gears pinion 19, mounted on a shaft carried A circular rack 18 is mounted upon in bearings on the under side of the turntable and provided with a worm-wheel 20. The worm 21, secured to the lower end of shaft 17, meshes into worm-wheel 20, and by this construction the turn-table may be rotated in either direction through the crank and gearing at the upper end of the vertical shaft.

The beam-supporting and beam-manipulating framework consists of two main standards 22 22 at each side of central shaft 6, which standards are secured to the upper side of the turn-table and are provided at their upper portion with pillow-blocks or bearings 23, in which is mounted the cross-shaft 24, provided atits middle portion centrallyabove the center of the machine with driving-pinions 25 in driving engagement with racks 26, secured to each side of the beam 27, the central web of which extends between pinious 25 and rests upon a roller 28, journaled on shaft 24, by which the Weight of the beam is carried and the teeth relieved from the strain of gravity. Above the beam is a roller 29, connected by links 30 to shaft 24, which roller provides an upper bearing for the beam and holds it in engagement with the driving-pin ions. The forward end of the beam is provided with a pivotally-attached rake-head 31, adapted to fold backwardly on coming into contact with the coke in entering the oven and to be automatically extended by tension of a spring 32 at the back end of the beam and connected with the upwardly-extending arms 34 of the rake-head by rod 33, passed through slot 35.

On each side of the beam, freely journaled on shaft 24, are the conical friction-drums 36, provided on their inner portions with peripheral beveled teeth 37, the teeth of both of such drums being in constant engagement with a driving bevel gear-wheel 38, secured to the upper end of the shaft 6, by which both friction-drums are constantly driven in opposite directions. The hub of each drum bears against a collar 39, secured to shaft 24, by which the drums are held in mesh with wheel 38.

Beyond the friction-drums on each side is asurroundingfriction-sleeve 40,each of which is provided with a hub portion in driving engagement with the shaft 24 by a spline or key 41, so that when either of such-sleeves is brought into frictional engagement with its drum by shifting the sleeve upon the drum it will transmit movement to shaft 24 in one direction or the other, according to which drum 36 is utilized. The shifting operation is secured through lever 42, pivoted at 43 and connected at 44 to a shifting bar 45, mounted in suitable hearings on the uprights 22 and provided with forks 46, engaging collars or flanges on the hub of sleeve 40, as clearly shown in Figs. 1 and 3. By this construction when the lever 42 is shifted in either direction but one of the frictionclutches will be engaged, and by adjusting the sleeves 46 so that in their intermediate position they are just clear of the friction+ drums the necessary movement of lever 42 is reduced to a minimum. Bythis means upon holding one of the clutches into contact the beam may be extended into the oven to the desired distance, and upon reversing the clutch it may be withdrawn as far as necessary by reason of the engagement of the pinion 25 in racks 26.

The inner end of the beam is raised and lowered by the rotation of shaft 47, the inner end of which is provided with a bevel-gear 48, in mesh with the upper and lower driving-bevels 49 and 50, loosely mounted on shaft 6 and provided on their inner portions with clutches 51, with which is adapted to engage a vertically-moving clutch 52, in key or spline engagement with the constantly running shaft 6.

Clutch 52 is normally out of engagement with either clutch 49 or and is raised or lowered by lever 53 engaging in a groove in the clutch, the lever being secured to shaft 54, mounted in hearings in the framework and provided with an operating hand-lever 55, extending upwardly within easy range of the operator. For the purpose of maintaining the lever 53 and clutch 52 in its normal middle inoperative position the shaft 54 is provided with a short arm 56, upon the outer end of which is hung a counterweight 57 by slot 58, elongated downwardly below the end of the arm. The counterweightslightly overbalances the weight of lever 53 and the suspended clutch 52 and rests on the turn-table, as shown. When the clutch is thrown down by the lever, the weight is raised from its bearing, and when the clutch is thrown up the arm passes freely down through slot 58.

Shaft 47 is mounted in suitable bearings, as shown, and is provided at its outer end with a worm 59 in engagement with a similarlytoothed segment 60, pivoted in the bearing-frame at 61 and provided with an extended lever-arm 62. Upward or downward movement of the outer end of the beam is imparted to it through arms 63, pivoted to lever-arm 62, carrying an under roller 65, upon which the beam rests, and bysupplemental links an upper roller 66. Links 67, pivoted at 68 in upwardly-extending guiding extensions 69,1naintain arms 63 and the supporting-roller 65 in an erect position during the raising and lowering movements of the beam. By these two movements the beam is thrust into or withdrawn from the oven and its operating-head raised or lowered. The movements are ordinarily independent of each other, although when the head is notin engagement with the coke it may be raised or lowered while the beam is traveling longitudinally in or out, the operator having simultaneous control of both levers-z'. e. lever 42 in the left hand and lever 55 in the right.

For the purpose of changing the angle of the beam with relation to the main supporting-frame and also to the central line of en- IIO . cated driven bevels 77 78, loosely journaled trance into the oven, so that the sides and 1 front of the ovens sufficiently below the door and adjacent to the front wall to support the machine in proper relation to the ovens.

For the purpose of moving the entire apparatus along the track, either for the purpose of locating it to the right or left of the central position in front of the ovens or for transporting it fromone oven to the other, one or more of the axles is positively driven by suitable gearing, and for this purpose I have employed a worm-wheel 73, preferably made in two halves and clamped or otherwise secured upon the axle, into which wheel meshes a Worm 74, mounted on the outer end of shaft 75, carried in suitable bearings and provided at its inner end with a bevel gearwheel 76, intermeshing with oppositely-loon shaft 5 and provided with friction or other clutch mechanism on their inner surfaces. Between -these driving-bevels, in spline engagement with shaft 5, is the movable clutch 79, adapted to be thrown into engagement with either driving-bevel by means of shifting lever 80, pivoted at 81 and connected by pitman 82 with bell-crank lever 83, likewise pivoted at 84 to the upper face of the main frame. The bell-crank lever 83 is provided with upwardly-extending lugs 85, between which pivotally engages the lower end of operating-lever 86, pivotally mounted at 87 in the upper supplemental stationary framework (1 of the machine, the lever extending upwardly within range of the operator, as clearly shown in Figs. 1 and 6, and

terminating in a handle 88. The lever 86 is provided with a hand-latch and locking-pawl 89, adapted to engage notches in segment 90 in a manner which will be readily understood. By shifting the lever 86 in either direction either of the clutches may be thrown into engagement and movement will be imparted to' shaft 75, resulting in the movement of the entire machine by traction either forward or back, and such movement is accurately controlled by the operator through the means just described. At the side of the machine adjacent to the oven is located the conveyer 0, into which the rake-head of the beam draws the coke from the oven. This con-' veyer consists of a series of slats9l, forming an endless apron passing around and carried by sprocket-wheels 92 and 93 in engagement with sprocket-chains 94, to which the slats are secured in the usual manner. The supporting-framework for the conveyer consists of two longitudinal members, preferably structural, as Ts 95, carrying a pan 96, having upwardly turned sides, the conveyerframework being carried by brackets 97, secured to and extending outwardly from the main framework, as clearly shown in Figs. 1 and 2. from shaft 5 through sprocket-wheels 98 and chain 99, passing around driven sprocketwheel 100 on one of the shafts'of the conveyer.

The conveyer 0 receives the coke from the oven and deliverslit into the receiving end of the conveyer D, arranged at right angles to conveyer 0 across the end of the machine and extending outwardly as far as may be desired to deliver the coke into an open-top car or upon the yard. This conveyer is in all respects similar to the conveyer 0, consisting of an endless slat belt supportedon' sprocket-wheels 101 and 102 by shafts mounted on longitudinal framework 103, similar to the other conveyer, the conveyer being driven from shaft 4 through sprocket-wheel 104 and chain 105, passing around driven sprocketwheel106, preferably secured to the shaftat' the outer end of the con veyer. The conveyer D may, if desired, be inclined so that its outer end will be sufficiently high to drop the coke into an open-top car bygravity.

The operation of the machine will be readily understood from the foregoing description.

The operator stands upon either there-- One end of the conveyer (l is driven erating fnnctions,'is within the control of one man.

The machine is very efficient in service, it

is capable of cleanly and thoroughly remov IIO use extending over a period of several months and whileI have found the details of the ap- I paratus to be efficientand mechanical in their design andoperation, it is obvious that variations, changes, and modifications may be made by the skilled mechanic in its various details, design, arrangement, or other particulars, and all such changes and variations are contemplated as within the scope of'ihe following claims.
